  "img_finding": "Image findings: ventricular volume measures 25,550 mm³, 14.4% above the reference mean. With a Z-score of 0.36 (64.1th percentile), this represents normal volume ; hippocampal volume measures 8,138 mm³, 5.9% above the reference mean. With a Z-score of 0.66 (74.6th percentile), this represents normal volume ; whole brain volume measures 1,083,060 mm³, 5.2% above the reference mean. With a Z-score of 0.65 (74.3th percentile), this represents normal volume ; entorhinal cortex volume measures 4,728 mm³, 21.5% above the reference mean. With a Z-score of 1.66 (95.2th percentile), this represents moderate enlargement; fusiform gyrus volume measures 18,617 mm³, 2.2% above the reference mean. With a Z-score of 0.25 (59.9th percentile), this represents normal volume ; middle temporal gyrus volume measures 17,158 mm³, 16.4% below the reference mean. With a Z-score of -1.46 (7.3th percentile), this represents mild atrophy. ",

  "gpt_diagnosis": "**Reasoning:** All brain volumes (ventricular, hippocampal, whole brain, fusiform gyrus) are within normal ranges except for mild atrophy in the middle temporal gyrus and moderate enlargement in the entorhinal cortex. Cognitive scores (MMSE 29, MoCA 28) are normal, and biomarkers (Aβ, T-tau, P-tau, AV45) are unremarkable.  \n\n**Diagnosis:** CN (Cognitively Normal)  \n**Confidence:** High",
